T0 all 'whom 'it may concern Be it known that 1, LEE M. VANCE, aciti- Zen of the United States, residing at Davis, in the county of Yolo' and State of California, have invented certain new and useful Improvements in Concrete- Post Machines, of which the following is a specification.

This invention relatesto an improvement in molds for concrete fence posts.

' rlhe primary object of the inventionlis to provide a mold which may be adjusted'to varythe dimensions and design of the post.

A further obj ect of the invention' is to provide a construction in which the operator may simultaneously apply pressure to the pallet and the top of the mold. f 7

A further object of the invention is to provide a post ejecting mechanism, the ejeetingmembers of which will be supported flush with the pallet and which may be operated to raise the post above the sidewalls of the mold. f

Another object of the invention is to provide meansfor imparting movement to the pallet throughout `its length which may be operated from both ends ofthe mold.

Another object of the invention is to provide means for limiting the movement of the pallet. ,Y

A still further objectv of the invention is to provide an actuating means for'the movable partsy of the mold and the post ejecting mechanism which may be operated from one end of the mold, the actuating levers being disposed so that the mold sections may be brought in contact with the concrete and the ejecting mechanism manipulated by one operator. 1

.to in the following description and indicated in all the views-of the drawings bythe same yreference characters.

'In the drawings, 10 designates the 'supporting frame which includes a plurality of i `PatentedJuly 27, 1915. l Application led ctober 22, 1912. Serial No. 727,258. f

12 andy with feet 1l. The supports at their Y upper ends are each provided with the substantially: U-shaped frame 15,"the portions 16 thereof which form connections between theU-shaped frame and theuprights 12, be-

ing formed with openings to receive bolts 17 .n

secured on the portions 16 of the framesl bybolts 17 inserted vthrough said apertures 24 ,and :the openings in said portions 16.`

The sides of the mold consists of plates 25, the upper edges of which are provided with longitudinalflanges or oifsets 26 disposed to rest upon the plates 23,` bolts 27 passing through the said flanges 26 and through said'plates. The, lower edge of each Vside plate. 25Yis flanged or offset, as at 28,said

offset .being more extensive than the iiange or offset 26 and provided with yapertures which receive the bolts 21. By this construction the side plates 25 arefadjustable transversely withres'pect to the plates 23 and base member 18, the plates 23 being adjustable on the intermediate rportions 16. of the supporting members to space the plates 25 so that the post formed in the mold will have the desired width. A pallet 30 is supported on the'offsets 28, said pallety adjacent the sides of the mold being formed with tapered or inclined walls B1, attention being called to the fact that these Walls maybe of any suitable configuration to vary the design of the post.

The base ymember 18 is formed with a series of vertical openingsV 32, through which Y ondseries of vertical apertures 35 through which extend rods 36. These rods are provided at `their upper ends with disks 37 e which are received within openings 38 formed in the pallet, the upper faces 89 of said disks being` then disposed flush with the face of the pallet. Thel rods 36 are raised afterthe post has been molded, the

disks 38 serving as ejectors to raise the post out'of the mold.

The pallet lifting rods 33 are actuated by levers 40 which are connected to the rod 41 which is suitably mounted for reciprocatory movement inthe main supporting frame.

The 'levers 40' are pivotally connected to the rod 41, a plurality rof* levers 42 connecting said'rod with collars 43 which embrace'the shaft 44. Y This shaft 44 is supported for rocking motion on the main frame,-the shaft turning freely within the collars 43. rod 41 is reciprocated by means of thelevers 45 to raise and lower the pallet supporting rods 33. These levers 45 are pivotally supported by ybrackets 46 and connected by links 47 with the-rod 41. Y It will be noted that as the lever 45 is moved in one direction the levers 40 and 42 will be disposed at right angles to the rod 41 and that the pallet will be raised.

The end sections 50 of the mold consist of U-shaped plates, the portion 51 'which connects theside walls52 thereof contacting with the end of thev post and the terminals 53 being secured Vto the portions 20 of the base member 18.

vBy the construction thus far described, the sides, bottom and end sections of the mold are provided. n

The top of the mold, which is movable vertically, consists of the longitudinal beam 54on the lower edge of which the top section 54 is carried, the beam being suspended for a vertical movement by a bea-m 56 to which is pivotally connected a plurality of links 57. These links are connected to the lrod 58 which is connected by a plurality of links 59 with the beam 54. The rod 58 is actuated by means of the lever 60 which is pivotally supported at 61 by the beam 56. V

It will be noted that as the lever 60 is `moved on its pivot the bar or beam 54 will be raised andlowered by means of the links 59. The top section 54 is guided in its vertical movementby the rods 55, the section being formed with the apertured ears 62 through which the rods 55 extend and said rods being rigid-with and rising from the supports 11 at the end of the mold. It will thus be noted that the top section may be raised and lowered in a simple and convenient manner, the terminal 63 of the lever The v on the base and top of the mold simultaneously.

With the mold arranged as shown in Fig. 5, the concrete is 4tamped in place. rl`he lever 60 is then actuated to force the top sectionv in contact with the concrete, after which the levers 45 and 60 may be moved to cause the pallet and the top section to approach each other1 whereby the concrete will be compressed and the post formed.

When the post has been molded and it is desired to remove the same from the mold, the mold ejecting members are actuated. The mold veiecting rods 36 are connected to the recurved link 65, the lower terminal of which is connected to the lever 66 which is secured to the shaft 44 whereby the ejecting members, which are disposed throughout the length ofr the mold, may be actuated, movement being imparted to the shaft by the lever 67, the terminalof which' is disposed adjacent the terminal 64 of the levei` 45. It will be seen by this construction that after the post has been molded, the mold may be opened and the post raised to a position where it may be removed, the entire manipulation of the operating mechanism being accomplished from one end of the mold.

The many advantages in a construction of this character will be clearly apparent as it will be noted that vthe construction is such as may be easily and economically manufactured and that the sections which form the mold may be readily adjusted to vary the size of the post. lt will also be seen that the mold sections may be provided with members for forming posts which vary in design and that the adjustment ofthe sections maybe accomplished without .removing the sections from the mold.
